FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 447,753, dated March10, 1891.

Application filed July 2, 1890. Serial No. 357,512. (No model.) I

To all whom it may concern.-

Be it known that I, BYRON BALDWIN, acitizen of the United States,residing at Brooklyn, county of Kings, State of New York, have inventeda certain new and useful Improvement in Win dow-Fasteners; and I declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being bad to theaccompanying drawings, which form a part of this specification.

My invention is designed to produce a window-fastener which shall be ofsuch construction that when attached to a window it will allow the lowersash to be raised or the upper sash lowered so far and no farther, andwill prevent the device from being disengaged and the windows freed,except when both sashes are closed.

The invention consists in a combination of devices and applianceshereinafter described and claimed.

In the drawings, Figure l is a part section of a window with my deviceattached thereto. Fig. 2 shows the construction in detail.

In carrying out the invention, A represents the upper sash, and B thelower sash, of the window.

0 is a suitable platerigidly engaged to the upper sash and provided withthe slot 0. The edges 0' of this slot are raised slightly from the mainportion of the plate, so that there is a recess between the edges of theslot and the sash. At the base of the slot is a widened portion D isanother plate rigidly engaged to the lower sash and provided with thelugs d. Pivoted between these lugs by the pivot d is one end of the rodE. The upper end of this rod is so formed that it will be engaged in andretained in the slot 0 of the plate C. There are various ways of soforming the upper end of the rod that this result may be obtained, thatshown by me being a convenient one, and consisting of making thediameter of the rod larger than the width of the slot, and thenproviding two grooves 6, one on each side of the end, which will fitonto and travel over the edges 0 of the slot 0. The widened portion a ofthe slot is wider than the diameter of the rod, so that when the end ofthe rod is lowered to this widened portion it can be withdrawn from theslot, and thus be disengaged from the plate.

In order thatthe distance to which the windows may be opened may beregulated, I provide the adjustable set-screw F, and by loosening andadjusting this to the height desired the play of the window may belimited as desired. So, also, in order that the operator may tell tojust what range of play his window is limited, I provide the face of theplate with graduations and indicate the distance by numbers. Th us thefigure 6 might mark a play of six inches, which the window is permittedto have, and the figure 9 nine inches, &c.

The operation of the device will at once be seen. The plate C is solocated on the upper sash that when the windows are closed the upper endof the rod will be at the lower end of the slot or at the widenedportion. When in this position, the rod can be swung away from theplate, and the window thus be free to be raised and lowered at will; butsupposing it is desired to open the window, say, for sake ofillustration, six inches,to allow for ventilation, the set-screw F isset at six inches, thus permitting the end of the rod to play freely upand down in the slot until it comes in contact with the set-screw, whenit can be raised no farther; or, supposing it is desired to allow thewindow to be raised twelve inches, the set-screw is then placed at 12and the window is permitted to be opened to that extent and no farther.By this arrangement,

as will be seen, a person can set his window,

say, at sixinches, which would not leave space for a person to enter,and obtain a good ventilation, while feeling himself absolutely securefrom any person opening the window from the outside and entering. hen itis desired to open the window to its fullest extent, all that isnecessary is to close both the upper and lower sashes, and then the rodmay be disengaged from the plate. In order that the rod cannot bedisengaged from the plate by jarring or otherwise, except from theinside, I extend the lugs (1 out somewhat and provide orifices (1through which apin (1 may be inserted, thus locking the rod in anupright position until the .pin is withdrawn.

It is, of course, obvious that the graduations on the face of the plateand the setscrew might be omitted and thelength ol the slot 0 be madepermanent. So, also, the various details of construction might bealtered without departing from the spirit of my invention.

\Vhat I claim is 1. The combination, with the upper and lower sashes ofa window, of the verticallyslotted plate 0, secured to the upper sash, aplate D, attached to the lower sash, and an upright rod E, pivoted atits lowerextreinity to the plate on the lower sash and having its upperextremity loosely ei'igaged with and sliding in the slotted part of theplate on the upper sash, substantially as described.

2. The combination, with the upper and lower sashes of a window, of theverticallyslotted plate 0, secured to the upper sash, a plate I),attached to the lower sash, an up right rod E, connected at its lowerextremity to the plate on the lower sash and having its upper extremityloosely connected with and sliding in the slotted part of the plate onthe upper sash, and a set-screw F, adjustable along the slotted plateabove the upper end of the upright rod to serve as an abutment for thelatter, substantially as described.

53. The combination, with the upper sash of a window, provided with theplate 0, having the vertical slot 0, and the rod 1), pivotally engagedto the lower sash, having its upper end engaged in said slot 0, of thepin (1 for retaining the rod in the slot a, substantially as described.

In testimony whereot I sign this specification in the presence of twowitnesses.

BYRON BALDWIN.
